Bad Breath (Halitosis)

Medically called halitosis, it can result from poor dental health habits and may be a sign of other health problems too.

Bad breath can also be made worse by the types of foods you eat and other unhealthy lifestyle habits.

How Does What You Eat Affect Breath?

Basically, all the food eaten begins to be broken down in your mouth. As foods are digested and absorbed into the bloodstream, they are eventually carried to your lungs and given off in your breath. If you eat foods with strong odors (such as garlic or onions), brushing and flossing — even mouthwash — merely covers up the odor temporarily. The odor will not go away completely until the foods have passed through your body.

Why Do Poor Habits Cause Bad Breath?

If you don’t brush and floss teeth daily, food particles can remain in your mouth, promoting bacterial growth between teeth, around the gums, and on the tongue. This causes bad breath. Antibacterial mouth rinses also can help reduce bacteria.

Did you know that persistent bad breath or a bad taste in the mouth may be a warning sign of gum (periodontal) disease?

Gum disease is caused by the buildup of plaque on teeth, when bacteria causes the formation of toxins to form, which in turn irritate the gums.

If gum disease continues untreated, it can damage further damage to the gums, jawbone and overall health.

Other dental causes of bad breath include poorly fitting dental appliances, yeast infections of the mouth, and dental caries (cavities).

The medical condition dry mouth (also called xerostomia) also can cause bad breath. Saliva is necessary to moisten the mouth, neutralize acids produced by plaque, and wash away dead cells that accumulate on the tongue, gums, and cheeks. If not removed, these cells decompose and can cause bad breath. Dry mouth may be a side effect of various medications, salivary gland problems, or continuous breathing through the mouth.

Many other diseases and illnesses may cause bad breath. Here are some to be aware of: respiratory tract infections such as pneumonia or bronchitis, chronic sinus infections, postnasal drip, diabetes, chronic acid reflux, and liver or kidney problems.
